Frequently Asked Questions

What is included in this Vaillant ecoFIT Pure 830 pack?

This restart pack includes the Vaillant ecoFIT Pure 830 30kW combi boiler, a horizontal flue kit and a 22mm Vaillant Advance system filter.

Is the ecoFIT Pure 830 suitable for my home?

The 30kW combi is commonly chosen for homes with one or two bathrooms and a reasonable simultaneous hot water demand. A Gas Safe registered installer should assess your property’s heat loss, gas supply, water pressure and existing pipework before installation.

Does this boiler need a hot water cylinder?

No. As a combi boiler, it heats domestic hot water directly on demand, so it does not require a separate hot water cylinder or cold water storage tank.

Why is the Advance filter included?

The Vaillant Advance filter helps protect the heating system by capturing magnetic debris such as magnetite and non magnetic sludge. Cleaner system water can support boiler efficiency and component longevity.

What warranty is available?

The boiler is supplied with a standard 2 year warranty, which can be extended to up to 10 years when installed with the Vaillant Advance filter and registered in line with Vaillant’s warranty terms and conditions.

Who can install this boiler?

Installation must be carried out by a Gas Safe registered engineer. The installation must comply with the manufacturer’s instructions, relevant Building Regulations and applicable UK safety standards.
